That doesn't mean it won't be back. You probably still have a N-E insulation fault on the installation which can can lead to it tripping from faults happening elsewhere!
And if the fault in another property is say on a light fitting and only present when its on, it'll be back again every evening!
That's a sweeping statement side that a tong tester IS not what many Sparks call it. I think you mean that's what YOU know it as. As it's a slang word it could mean anything.
Such as side cutters are sometimes called snips, cutters, nips, chomps.
I know what you mean tho, I'd frown if you called a clamp on meter a tong tester. Oops

i guess its the reaction you have to a caggy hander.
